In a new interview with Zack Snyder, HeroComplex got some new details and teases about the still untitled sequel to Man of Steel.

The movie, which “literally takes the Man of Steel and Batman universes and explodes them,” starts filming in “a month or so,” says the director, who also added that pre-production is “going great.” His first big moment? Testing the suits on camera.

”The new Batsuit and the Superman suit. It wasn’t even with the actors, right? It was just to see ‘em. I was standing there, they were standing next to each other. And I was like, ‘Guys, someone take a picture! This has never happened before.’ We slightly dork out. Like, ‘Are you kidding me?!’”

Chris Lee of HeroComplex did address the elephant in the room of internet backlash over casting decisions, and Snyder vehemently defended their choices.

”We know the material. Unfortunately, the fans don’t know the material. So, we’re casting according to what’s happening in the script. And we’re hoping that leads to enough originality, enough perspective on what we’re doing that you get something fresh and exciting,” Snyder said.

Ultimately, his excitement over the film is easy to see in his comments, saying, “when you think about how fun it is too — now that you’ve got these characters — to now let ‘em loose. That’s fun!”
